Participants: Takahashi, Aso, Ushiba, Yokozawa, Hirata, Ikeda, Sato, Mitsuhashi

Acceptance check document

Suspensions

  • Type-A: Height adjustment of ETMX. Offload in IX and EX. Elena-san will try to damp ITMX.
  • Type-B: Measurement on the sensor correction in SR2.
  • Type-Bp: Test of damping control.
  • Type-C:

Other items

  • Oplev: Check of TM Oplev in EX.
  • ACC:
  • Commissioning:
  • Vacuum system: Waiting for the GV opening in EX.
  • Heater control:
  • TMS:

Post O4a

  • Measurements of the DAC noise: Type-C.
  • Measurements on the sensor correction in SR2: Performed by Terrence on 9/12.
  • Optimization of the damping control in PRs: Tested for PR3 and PRM on 9/12.
  • IP control with the ACCs: One more test is necessary.
  • In-vacuum accelerometer for IOO: Leak test of the pod is planned in early October.
  • Hight adjustments of Type-A in the cooling: Monitoring from 9/8.
  • Temperature control for the Oplev: Prepare for IXC and EXC.
  • TM cooling: Schedule.
  • IM heater: Setup for IX and EY was finished.
  • OMC damper: The parts should be prepared by 9/13.

Discussion

VIS Meeting

Date: 2023/9/22 10:00-10:45

Participants: Takahashi, Tanaka, Sato, Ushiba, Hirata, Mitsuhashi

Summary Report

Type-A

  • Height adjustment of ETMX.

Type-B

  • Measurement on the sensor correction in SR2 by Terrence.

  • Damping of the OMC suspension.
    • Production of the blade damper.
    • Prototype test of the flexible pendulum damper.

Electronics

Control

R&D

  • TAMA-SAS experiment: TF measurement of IP+RL.

Schedule
